Article 6: Development Standar <br /> Section 6.14:Stormwater Management <br /> (C) Periodic corrective action to restore dispersed#u&@ flow shall be taken if necessary to <br /> impede the formation of erosion gullies. <br /> 6.13.8 Land Disturbance and Planting of Vegetation <br /> (A) Area within a stream buffer which is subject to serious erosion may be disturbed for the <br /> purpose of planting and maintaining erosion-resistant vegetative cover. <br /> (B) Existing forested areas or any other healthy vegetation may not be removed from a <br /> stream buffer, except where replaced with vegetation resulting in comparable stormwater <br /> runoff velocity and quantity one year after planting. <br /> (C) New vegetation shall be planted to capture non-source pollutants before they reach the <br /> perennial stream, as per applicable Orange County Standards. <br /> STORMWATER MANAGEMENT Introduction <br /> As a watershed becomes more developed, the amount of impervious surface area increases, <br /> causing a decrease in the rate at which stormwater runoff which can be absorbed into the soil. <br /> This results in more-additional149 stormwater runoff150 flowing directly into streams and other <br /> water bodies. Because this additional 151 direct stormwater runoff has not been filtered through <br /> the soil, pollutants from the air and land surface enter streams and increase the potential for <br /> pollution of hydrologically connected aquatic ecosystems and 152 drinking water supplies. <br /> 6.14.2 Purpose <br /> It has been determined that proper management of construction-related and post-development <br /> stormwater runoff will minimize damage to public and private prosy and infrastructure: <br /> safeguard the public health, safety, and general welfare, and protect water and aquatic <br /> resources.153 The purpose of the Board of County Commissioners in adopting stormwater <br /> management regulations is to protect the water quality of the streams that He within Oranae <br /> ounty by reducing and controlling stormwater runoff and addressing nutrient reductions for bot <br /> new and existing development. <br /> 6 1426.14.3 Jurisdiction-Wide and Inter-Local Approaches <br /> (A) Orange County shall have the option of implementing jurisdiction-wide and/or inter-local <br /> approaches to control stormwater runoff and achieve nutrient reductions. <br /> 149 Text correction-replaced"more' with "additional". <br /> 110 Consistentuse ofthe term "stormwater runoff'-NOTE. "stormwater runoff"is integrated throughthe <br /> remainder of Section 6.14,where applicable. <br /> 151 Text correction-added "additional". <br /> 152 Added "hydrological ly connected aquatic ecosystems"-NOTE. This is a staff recommendation to help the <br /> general public understand that Orange County is not just trying to protect human focused drinking water <br /> supplies, but also our aquatic ecosystems that are hydrologically connected. <br /> 153 This languagewas pulled directlyfrom the Falls Lake Model Ordinance;provides greater context in Purpose. <br /> Orange County, North Carolina- Unified Development Ordinance Page 6-97 <br />
